- Fix a bug when adding an interface with an invalid MTU sets the
bridge's MTU if it is the firstly-added one while the addition
itself fails.
- Allow SIOCSIFMTU only when all members have the same MTU.
- Remove IFT_GIF check when defining the brige MTU by the
firstly-added interface's one. The MTU of the gif interface
has to be the same as the bridge's one.
Fix a long standing regression of readdir(3) in fdescfs(5) introduced
in r1.48. We were stopping at the first null pointer when multiple file
descriptors were opened and one in the middle was closed. This restores
traditional behaviour of fdescfs.
Tidy up callout for select(2) and read timeout.
- Add a missing callout_drain(9) before the descriptor deallocation.[1]
- Prefer callout_init_mtx(9) over callout_init(9) and let the callout
subsystem handle the mutex for callout function.

Move the OEA64 scratchpage to the end of KVA from the beginning, and set
its PVO to map physical address 0 instead of kernelstart. This fixes a
situation in which a user process could attempt to return this address
via KVM, have it fault while being modified, and then panic the kernel
because (a) it is supposed to map a valid address and (b) it lies in the
no-fault region between VM_MIN_KERNEL_ADDRESS and virtual_avail.
While here, move msgbuf and dpcpu back into regular KVA space for
consistency with other implementations.
Provide an implementation of pmap_dev_direct_mapped() on OEA64. This is
required in order to be able to mmap the running kernel, which is turn
required to avoid fstat returning gibberish.
Close a race involving the OEA64 scratchpage. When the scratch page's
physical address is changed, there is a brief window during which its PTE
is invalid. Since moea64_set_scratchpage_pa() does not and cannot hold
the page table lock, it was possible for another CPU to insert a new PTE
into the scratch page's PTEG slot during this interval, corrupting both
mappings.
Solve this by creating a new flag, LPTE_LOCKED, such that
moea64_pte_insert will avoid claiming locked PTEG slots even if they
are invalid. This change also incorporates some additional paranoia
added to solve things I thought might be this bug.

Reduce KVA pressure on OEA64 systems running in bridge mode by mapping
UMA segments at their physical addresses instead of into KVA. This emulates
the direct mapping behavior of OEA32 in an ad-hoc way. To make this work
properly required sharing the entire kernel PMAP with Open Firmware, so
ofw_pmap is transformed into a stub on 64-bit CPUs.
Also implement some more tweaks to get more mileage out of our limited
amount of KVA, principally by extending KVA into segment 16 until the
beginning of the first OFW mapping.

PVOs, and so the modified state of the page can no longer be communicated
to the VM layer, causing pages not to be flushed to swap when needed, in
turn causing memory corruption. Also make several correctness adjustments
to I-Cache synchronization and TLB invalidation for 64-bit Book-S CPUs.

Place interrupt handling in a critical section and remove double
counting in incrementing the interrupt nesting level. This fixes a number
of bugs in which the interrupt thread could be preempted by an IPI,
indefinitely delaying acknowledgement of the interrupt to the PIC, causing
interrupt starvation and hangs.

Provide thermal management and monitoring features in smu(4). This allows
fan control and thermal monitoring on SMU-based Apple G5 machines, as well
as an led(4) interface to control the sleep LED.
- Added a workaround for NC-SI management firmware that would allow
frames to be accepted while the driver is resetting the hardware.
This failure is generally observed when broadcast frames are received
during driver load and will generate "Unable to write CTX memory"
errors.
- Small changes to driver flags display.

According to the Linux sungem driver, in case of Apple (K2) GMACs
GEM_MIF_CONFIG_MDI0 cannot be trusted when the firmware has powered
down the chip so the internal transceiver has to be hardcoded. This
is also in line with the AppleGMACEthernet driver, which just doesn't
distinguish between internal/external transceiver and MDIO/MDI1
respectively in the first place. Tested by: Andreas Tobler
When a kinfo_proc is filled, first fill_kinfo_proc_only() fills in
ki_runtime using p->p_rux.rux_runtime (all cpu time used by the process
including terminated threads). If information for a specific thread is
requested, fill_kinfo_thread() then overwrites this with the thread's
td->td_runtime (good). If not, fill_kinfo_aggregate() overwrote it with
the sum of all threads' td->td_runtime which does not include terminated
threads.
This affects ps(1)'s TIME field, not its %CPU field nor anything in
top(1).

Change the way shutdown is handled for log file.
pmc_flush_logfile is now non-blocking and just ask the kernel
to shutdown the file. From that point, no more data is
accepted by the log thread and when the last buffer is flushed
the file is closed.
This will remove a deadlock between pmcstat asking for
flush while it cannot flush the pipe itself.
